RE: Eico HF-30 question

Hi, Michael, and thanks! This was originally the 6AV6/6C4 version that someone in the past had wired up the PS to be the version with the 7247, don't really see a problem with that. The plate and screen is right on the money, the rail after the 33K is 281 v, whereas the schematic notes 310, this is for the 7247 version, don't know what the voltages are supposed to be for the 6C4/6AV6 version (this voltage feeds the front end tubes) Also, the cathode for the 6BQ5 is 11.6 v, once again I don't know what it should be for the 6C4/6AV6 version, but the 7247 schematic it is 15 volts. Thanks, Randy
